NUTRITN 230 Lecture Notes - Lecture 13: Lipoxin, Blood Vessel, Thromboxane
Document Summary
Indicated where the first double bond closest to the methyl end of the chain occurs. Our bodies are unable to synthesize essential fatty acids with a double bond before the. 9th carbon in the chain, counting from the omega end. Need to be provided in our diet. 18 acrbon chain, 3 cis double bonds, first double bond between the 3rd and 4th carbons. Converted to the other omega-3 fatty acids. Eicosanoids: hormonelike compounds such as prostaglandins, prostacyclins, thromboxanes, leukotrienes, and lipoxins. Crucial for brain function and growth and development. Reduce inflammation, anti blood clotting, blood vessel relaxation. 18 carbon chain, 2 cis double bonds, first double bond between the 6th and 7th carbons. Also important for brain function and growth development. Too much can cause inflammation and blood vessel constriction. Regulatory molecules synthesized from omega-3 and omega-6 fatty acids. Help regulate blood pressure, blood clotting, sleep/wake cycles, body temperature, inflammation, stomach secretions and immune and allergic responses.
